A new study has shown that there are different types of European cisco in Swedish waters that are each genetically adapted to fresh, saline or brackish water. Genetics also steers where European cisco spawn. The new knowledge from this study can be used in continuing the sustainable management of the species, and for investigating whether the spawning environment affects the quality of the roe.
Heatwaves, droughts and forest fires are some of the extreme climate-related events that are expected not only to become more frequent but also to increasingly strike at the same time. This finding emerges from a new study led by Uppsala University, in which researchers have mapped the impact of climate change in different regions of the world.
Different species of seabirds can coexist on small, isolated islands despite eating the same kind of fish. A researcher at Uppsala University has been involved in developing a mathematical model that can be used to better understand how this ecosystem works.
Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having shrunk and the number of trees having fallen sharply during ice age cycles. These are the findings of a study jointly led by Uppsala and Helsinki Universities, published in Nature Communications.
Krill in our northern waters show how key marine species can adapt genetically to cope with climate change. This is the discovery made by researchers at Uppsala University in collaboration with an international research group. According to the researchers, their study, published in Nature Communications, provides important knowledge that can help protect marine ecosystems when the climate changes.
Given the volcanic activity on Iceland over the last three years, researchers from six universities anticipate recurring, moderately sized eruptions of similar style in the coming years to decades. They therefore stress the need for preparedness in view of the risks posed to local populations and critical infrastructure. Their study was recently published in the scientific journal Terra Nova.
Rabbits have colonised countries worldwide, often with dire economic and ecological consequences, but their secret has before been a mystery. In a new study published in the journal Nature Ecology and Evolution, an international consortium of scientists sequenced the genomes of nearly 300 rabbits from three continents to unveil the key genetic changes that make these animals master colonisers.
Researchers have discovered that bank voles in Skåne, southern Sweden, carry a virus that can cause hemorrhagic fever in humans. This finding was made more than 500 km south of the previously known range. This is revealed in a new study from Uppsala University. The researchers were surprised that such a high proportion of the relatively few voles they caught were actually carrying a hantavirus.
Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study by Díaz et al. (2024) reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.
The European robin’s closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance. This is confirmed by a new study of the Old World flycatcher family, to which these birds belong. The study comprises 92 per cent of the more than 300 species in this family.
The effects of the endocrine disruptor linuron on frogs are not limited to those exposed, but are passed on to their offspring (reduced body weight and decreased fertility) and grand-offspring (increased body weight and a disrupted metabolism). This is demonstrated by a new study (Uppsala University and Stockholm University), published in the journal Science of the Total Environment.
Pool frogs infected with the parasitic chytrid fungus Batrachochytrium dendrobatidis range over shorter distances. This is the conclusion of a study conducted by researchers at Uppsala University and the Swedish University of Agricultural Sciences (SLU), who have investigated how the fungus affects the mobility of the red-listed pool frog along the Uppland coast.
In a new study researchers have found that although warmer weather should benefit badger populations, the predicted human population increase in the Scottish highlands is likely to disturb badgers and counteract that effect. These results emphasise the importance of interactive effects and context-dependent responses when planning conservation management under human-induced environmental change.
In a collaborative effort, researchers at Uppsala and Umeå University now show that the formation of methylmercury in sediment is controlled by the molecular composition of the organic matter. The study has been published in Nature Communications.
Researchers at the Chinese Academy of Sciences in Beijing and Uppsala University, Uppsala, Sweden have put together all known information about the endangered Rufous-headed Robin. Very few observations have been made since it was first discovered in 1905. The researchers suggest that its distribution might be larger than previously thought.
For the upcoming Uppsala Health Summit on antibiotic resistance, 2–3 June, a report has now been published focusing on some of the most pressing issues and challenges. The aim of the meeting is to move the discussion forward, from the ‘what’ to the ‘who’ and ‘how’.
It has long been known that the characteristics of many plants with wide ranges can vary geographically, depending on differences in climate. But changes in grazing pressure and pollination can also affect the genetic composition of natural plant populations, according to a new study.
